i7 6700k now always at full speed and hot

Superlevure · 27 Mar 2016 at 06:44

Hi everyone,

I installed windows 10 and reinstalled the AI suite III that came with my Asus Z170 Pro gaming.

The CPU is now always at 4ghz (or 4.2 when I did a light OC) and 42 degrees when idle.

Before, the CPU used to sit at 30 degrees. It used to lower / increase its frequency according to my usage, and I could even set the fans to silent (with all fans off, except for the CPU). If I do that now, it will go up to 50 degrees, which it could only get to when I was playing 3D intensive games.

What am I forgetting?

Do you have speedstep/shift enabled in the bios? also go into Control Panel\System and Security\Power Options and set power plan to balanced (thats how to in windows 7).

Let me guess - you used AI Suite to do that mild overclock?

If so, uninstall AI Suite, along with taking khemist's advice. Reinstall again later if you like but only to mess with fan profiles. Do any overclocking from within BIOS.

If you didn't use AI Suite to overclock, ignore.

It did it, thank you.

In that menu, the power options were a) Balanced (recommended) or b) Power saver

I really would have thought Power saver was what I was looking for. I selected Balanced as you said, everything went bac to normal. under Windows/idle.

I'll test that in a game situation.

Thanks a lot.

I use AI suite to adjust the multiplying factor (42 instead of 40) and tweak the fans. Why do you recommend against it?

Blue screens, applying of changes you don't want along with those you do, etc. It happened to me with a build and forums are full of examples of it happening to others. Then problems with uninstalling it, even the official Asus uninstaller sometimes won't work. It's been responsible for many a clean install of Windows.

It's probably what altered your power settings when you increased multi. Unless you tinkered with an SSD program like Samsung Magician or something.

Anyway, making the change in the actual BIOS instead of through Windows, is much better/avoids possible issues with software such as AI Suite.

I've had the problems when uninstalling, it was a real chore - and this is on a recent sytem (Win 8.1, Asus z170 and latest version of AI Suite III)

No blue screens though. Yet.

That's as maybe, but Danny is correct in what he says. Overclocking should always be done through BIOS if you want it to be stable.
